A:Answer Hello,
If the Samsung Soundbar "works with Alexa" or has Bluetooth technology, then you would be able to pair the Show 10 with the soundbar, and what you asked Alexa to do, the sound would then come from the soundbar. As far as mimicking the screen of the Show 10 to the TV, there are no inputs or outputs from the back of the show 10 device, and screen mirroring is not an option on the Show devices as of now. The ability to connect the Echo to the Smart TV is just to voice control the functions that the TV allows, such as some allow power control, some allow you to change input and volume control, or find smart apps such as Netflix and Hulu that are built into the menu of the actual TV. I hope some of this information helps.
